We could argue (and agree) that Canada isn’t major, but their central bank sold off their bullion gold reserves ~ 2 decades ago. And finished off its hodl of gold coins ~7 years ago.
Canada did it to increase diversity of investment "investing in financial assets that are easily tradable and that have deep markets of buyers and sellers"
The truth is probably based on the money they received from selling the gold as a retail coin
